I was at my wits end. I dyed my dark brown hair blonde but it always ended up a orange tinted brassy color. I lived with it for awhile and then tried to go back to dark but I just don't like it as much as the blonde. So after trying purple shampoo, different colors, and a few other things I did some research on how to get rid of the brassy and found this product. All I can say is yeah! Finally the brass is gone. It's a lovely shade of ash blonde and I love it. I realize everything doesn't work on everyone but I say try it at least. It may just do the trick.
